UltraCosmetics GUI Addon

UltraCosmetics GUI Addon is an addon for UltraCosmetics that customizes the main and purchase menus with custom textures. Thanks to @dennishzg for creating the resource pack!

🛠️ How to use

Add server resource pack

By default, once the plugin is installed, it will suggest to clients to install the resource pack. Alternatively, you can disable that in the config and distribute the resource pack yourself; it can be downloaded in the Releases tab.

Create menu

If you have a custom menu for UC, you can also use these textures there. Example menu using DeluxeMenus:

GUI texture

  • 🏠 = Main menu texture
  • 🪙 = Buy menu texture
size: 54menu_title: "&f🎲🎲🎲🎲🎲🎲🎲🎲🏠"

Custom items

Example:

/minecraft:give @p minecraft:brick[minecraft:item_model="ucgui:uc_items/key"]
ImageItem modelDescription
invisibleucgui:guis/invisibleitemInvisible items are necessary to make the buttons/icons in the GUI clickable.
Keyucgui:uc_items/keyTreasure chest key

✅ Compatibility

UltraCosmetics GUI Addon officially supports both Spigot and Paper.

The resource pack is designed for clients 1.21.4 and up.

🛠️ How to use
Add server resource pack
By default, once the plugin is installed, it will suggest to clients to install the resource pack.
Alternatively, you can disable that in the config and distribute the resource pack yourself; it can be downloaded in the Releases tab.
Create menu
If you have a custom menu for UC, you can also use these textures there. Example menu using DeluxeMenus:
GUI texture
  • 🏠 = Main menu texture
  • 🪙 = Buy menu texture
size: 54menu_title: "&f🎲🎲🎲🎲🎲🎲🎲🎲🏠"
Custom items
Example:
/minecraft:give @p minecraft:brick[minecraft:item_model="ucgui:uc_items/key"]

ImageItem modelDescription
invisibleucgui:guis/invisibleitemInvisible items are necessary to make the buttons/icons in the GUI clickable.
Keyucgui:uc_items/keyTreasure chest key
✅ Compatibility
UltraCosmetics GUI Addon officially supports both Spigot and Paper.
The resource pack is designed for clients 1.21.4 and up.
